2. Easy to operate.
3. Several type transducer s for selection, measuring pipe size is from DN15mm to DN6000mm
4. Adopt low voltage, multi-pulse technology to improve accuracy, useful life and reliability.
5. Powerful Recording Function, record the totalizer data of the last 64 days/64monthes/5 years.
Description:
The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and easy installation. The TF -2000S transit - time flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers can be mounted in V- method where the sound transverses the pipe twice, or W- method where the sound transverses the pipe four times, or in Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once.
This selection of the mounting method depends on pipe and liquid characteristics. The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers. The difference in the transit time measured is directly and exactly related to the velocity of the liquid in the pipe, show as follows:
Where
Where hereθis the include angle to the flow direction, M is the travel times of the ultrasonic beam, D is the pipe diameter Tup is the time for the beam from upstream transducer to the downstream one Tdown is the time for the beam from downstream transducer to the upstream one
Δ T=Tup – Tdown
Applications:
It can be used in water, heating, water conservancy, metallurgy, chemical industry, machinery, energy and other industries. Also can be used as production monitoring, flow quantity checking, temporary detection, traffic inspection, water balance test, thermal net balance debugging, energy monitoring, detecting when flow is necessary tool instrument.
